SHEET-GLASS COOLER.

' Application filed October 13, 1924. Serial No. 743,226.

The present invention relates to an improved cooler and has reference to a cooler particularly well-adapted for use in connection with sheet 'lass drawing apparatus.

An important ob ect of the invention is to provide a cooler for use in connection with sheet glass drawing apparatus wherein a continuous circulation of cooling medium is had so that the possibilities of the cooler clogging up and bursting are remote.

A further object of the invention is to provide a cooler having a tortuous passage for a cooling medium whereby the cooler can be associated with the tank wall and the l5tongue arch of sheet glass drawing apparatus in a manner to prevent deterioration of these members due to the terrific heat to which they are exposed.

A still further object of the invention is to provide a cooler of this nature wherein a continuous flow of water is passed therethrough in a manner to prevent formation of steam pockets and the like which are detrimental to the action of such coolers.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings wherein like numerals are employed to designate like parts throughout the same- Fig. 1 is a longitudinal section through a portion of the apparatus for drawing sheet glass showing the coolers in conjunction with the tank wall and tongue arch,

In the drawings wherein for the purposes of illustration is shown the preferred embodiment of the invention, numeral 10 desigto notes a portion of a sheet glass drawing Fig. 4 is a fragmentary sectional view apparatus and includes a tank 11 having a source of molten glass 12'arranged therein. Ordinarily the glass 12 is heated by means of gas flames. In the type of machine illustrated the flames are played upon the glass, first at one side of the machine and then at the other side. In other words, heating is accomplished by having sets of burners on both sides of the tank 11. During the time for instance that the left hand burners of the furnace are going the exhaust therefrom will pass through the conduits 18 and heat the checker-work 14 so that when the burners at the lefthand side of the furnace are cut off and the burners at the righthand side placed in operation, the air drawn up through the checker-work 14: will be sufficiently heated to aid combustion of the gases fed through the port 15, thus giving an exceptionally hot flame with a minimum amount of waste. The tongue arch 16 is exposed to very high temperatures, and to prevent disintegration thereof, it is necessary to place a cooler at, one end as shown in Fig. l to protect the same. Due to the inconvenient loeation of the cooler at the end of the tongue arch it is desirable to have one that will withstand the terrific heat for a considerable length of time to prevent constant replacement.

In addition to the burning away of thetongue arch'the walls of tank 11 are gradu- M ally decomposed as at 17 until eventually the entire wall is gone. To offset this tendency it is necessary to place coolers on the outside of the wall as shown in Fig. 1 to chill the same.

In order to provide satisfactory coolers it is necessary to' have a cooler in which a continuous circulation of a cooling medium can be had. In many types of coolers steam pockets, etc. form therein, thus causing a poor circulation and clogging up of the cooler with resultant blowing up of the same.

In the present form of the invention I construct a cooler from a plurality of substantially cylindrical sections'18, which are arranged in substantial parallel relationship. In Figs. 6, 7 and 8, the details of the construction are shown, wherein the ends of the sections 18 are split along a line as at 19 for a substantial distance. The section is then cut at right angles as at 20 approximatel half way through the section, after whie' the lips 21 are bent up and beveled as at 22. As seen in Figs. 7 and 8 lips of the same ends of adjacent sections are welded together as at to provide awater-tight joint, after which a cap or plate 23 is welded in the ends to close up the sections. The spaces or gaps 27 formed between the inner ends of the lips 21 and the'cylindrical sections 18 can be closed by welding the said lips and sections together or if desired, plates or the like 26 can be welded or otherwise suitably secured within the said spaces or gaps.

As shown in Fig. 2 the cooling medium is introduced in one of the outermost sections and flows therealong to its opposlte end where it passes down'into the adjacent section and so on through the various sections ing one, thus preventin until it passes out through the exhaust. It will be seen that this arrangement of cooler provides a tortuous passage for the coolingmedium sothat' there is a continuous flow. Que to the fact that the sections 18 are formed from substantially cylindrical material, the, cooler will be ineffect a self-flushaccumulation of sediment or the like, so t at the cooler will at all times be kept free from dirt and steam pockets so that under ordinary conditions the chances for blowing up of the cooler are rather remote.

In order to adapt the cooler to the curvature of the tongue arch 16, it is necessary'to curve the same as shown in Fig. 2. In both types of coolers the circulation'is identical.

In the foregoing it will be seen 'that a cooler formed inaccordance with the present invention will provide a tortuous passagev for a cooling medium'while at the same time the cooler will be continuously flushed due to the cross-sectional shape of the members from which the cooler is formed.

It is to be understood that the form of the invention herewith shown and described connecting one end of each member with an end of one adjacent member, and the opposite end with the other adjacent member to form a tortuous pamage for the flow of a cooling medium therethrough.

2. In combination with a sheet glass machine, a cooler comprising a plurality of separate cylindrical sections arranged in parallel relationship, each section contacting with its adjacent sections, means 'for connecting the sections in a manner to form a tortuous passage for a flow of a cooling medium, the cooler as a unit having but a single inlet and a single outlet.

3. A cooler for use in glass apparatus, comprising a plurality of separate eylindrical members arranged in parallel relationship, each member contacting with the ad acent members, one end of each member and the same end of one adjacent member being provided with lips, the lips of said members being directed towards and secured to one another, and means for plosing the ends of said members.

4. A cooler for use in glass apparatus, comprising a plurality of separate cylindrical members arranged in parallel relation ship, each member contacting with the adjacent members, one end of each member and the same end of one adjacent member being directed towards andsecured to one another, fneans for closing the ends of said members, and means for closing the spaces between the inner ends of said lips and members.

5. A cooler for use in glass apparatus,

comprising a plurality of separate cylindrical members arranged in parallel relationship, each member contacting with the adjacent members, one end of each member and the same end of the adjacent member at one side thereof bein provided with lips, the lips of said members being directed towards and secured to one another, the opposite end of each member being provided with similar lips directed in the opposite directionto the lips at the other end thereof and secured to corresponding lips formed at the same end of the adjacent member at the opposite side thereof, and means for closing the outer ends of said members.

6. A cooler for use in glass apparatus, comprising a plurality of separate cylindrical members arranged in parallel relationship, each member contacting with the adjacent members, one end of each member and the same end of one adjacent member being split longitudinally and cut transversely at the inner end of the split to provide a pair of lips, the lips of said adjacent members being directed towards and secured to one another, a single closure secured'to the outer ends of said lips, and means for.

closing the spaces between the inner ends of said lips and said members.
